Pet Probiotic Supplement
[INQ. NO. 2508C01] GUARDIZEN is a specialized veterinary product designed to enhance the intestinal health of companion animals such as dogs and cats. It combines two core functional ingredients: probiotics and IgY (immunoglobulin Y) derived from egg yolk.
This unique formulation provides both digestive support and immune defense, particularly for young pets that are vulnerable to infectious diseases before or during vaccination.
The key ingredient, IgY, is an egg yolk-derived antibody obtained from hens immunized against specific viral pathogens. These include canine parvovirus (CPV), canine distemper virus (CDV), infectious canine hepatitis (ICH), canine parainfluenza virus (CPIV), and canine coronavirus (CCV).
For felines, it protects against panleukopenia, rhinotracheitis virus, and calicivirus. This form of passive immunity offers critical protection for puppies and kittens, particularly those who are not yet vaccinated or are under immunological stress.
The probiotic component in GUARDIZEN consists of seven beneficial live bacterial strains that promote a balanced gut microbiome. This not only enhances digestion but also supports stress management, which is crucial for maintaining overall health in pets.
The supplement is easy to administer—each 1-gram sachet is mixed with the animal’s food or drinking water once per day.
GUARDIZEN is currently exported to multiple countries, including Myanmar, Indonesia, Vietnam, Taiwan, Malaysia, the Philippines, and the UAE. It has gained strong market traction due to its noticeable efficacy, ease of administration, and superior palatability, which sets it apart from competitors.

Livestock Reproduction Hormone
GONADON is a veterinary pharmaceutical product formulated to manage and improve reproductive performance in livestock, particularly cattle and swine. The active ingredient, Gonadorelin, is a synthetic version of gonadotropin-releasing hormone (GnRH), naturally secreted by the hypothalamus.
This hormone acts on the pituitary gland to stimulate the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which are essential for reproductive health and efficiency.
In dairy cattle, GONADON supports the growth and maturation of ovarian follicles, stimulates estrogen production, and promotes ovulation. It is widely used to treat conditions like ovarian cysts, silent estrus, and delayed ovulation. The product is also used in synchronization programs to coordinate estrus and ovulation for more efficient breeding.
In swine, particularly sows, GONADON aids in ovulation induction, estrus synchronization, and fertility enhancement. By controlling the hormonal cycle, it ensures higher conception rates and improved productivity. Its targeted use helps reduce reproductive downtime and contributes to better herd management.
GONADON is manufactured in Korea’s only GMP-certified facility dedicated to hormone pharmaceuticals. This allows for superior quality assurance and production consistency. In addition to its proven clinical efficacy, the product is competitively priced and supported by comprehensive technical and customer service.

The product is exported to numerous countries including Vietnam, Myanmar, Sri Lanka, Indonesia, Ukraine, and the UAE. The company’s participation in global exhibitions and seminars has further reinforced the product’s presence in international markets.
